In a series of family pictures, Jessica shared images of Haven’s first birthday party, and a shot of big sister Honor, 4, dressed up as a mermaid.

When baby Haven arrived one year ago, the Fantastic Four star shared her joy via Facebook.

“She was born on Saturday, weighed 7 lbs and was 19 inches long,” she wrote. “Healthy and happy! Big sister Honor couldn’t be more excited about the new addition to our family. Thank you for all of your support during my pregnancy. It means the world to me.”
